Aye, mate! How are ya?
Thanks for your detailed review! I appreciate the time you put on it. I'm really, really glad you enjoyed our art.
It's our second Jam so we had a few problems with managing time (me, particularly). Therefore, this resulted in the problems you're facing:
1. We should have added a couple of introductories levels explaning the mechanics... but the idea was to get a sheep at a time.
2. Probably a bug on your end... we should have tested more to find it.
3. The idea was to give a reward if the player find the shortest path... Like, a single star for completing the level and 2 stars if find the optimal path. That is the puzzle.
Despite those minor issues, I'm glad that you enjoyed a bit!
